Bug in history.php

[globlalways]

I request the following URL:
/history.php?period=7200&dec=0&inc=0&left=0&right=0 &stime=yyyymmddhhmm&itemid=28393&action=showgraph& from=0

The graph is not beeing displayed correctly, because the url for the image is not correct:
/chart.php?itemid=28393&period=yyyymmddhhmm&from=0& width=1172

As you can see the period parameter is not correct in the source. Is this a known bug?

I figured out that this is a bug, how the show_history function is called:

Wrong:

show_history($_REQUEST["itemid"],$_REQUEST["from"],$_REQUEST["stime"],$effectiveperiod);

Correct:

show_history($_REQUEST["itemid"],$_REQUEST["from"],$effectiveperiod);

I cannot confirm this, ZABBIX 1.1.4 works absolutely fine with this URL. Your fix is incorrect as show_history() accepts four parameters, not three!
